Application
Shipboard telecommunications cable for fixed installation at all ship’s levels (including outer deck where it needs to be protected against UV irradiation) acc. to IEC 60092-352 standard, in circumstances requiring fire resistance. Specially suitable for passenger ships because of improved characteristics under fire. Also applied at open sea platforms. Copper braid acts as reinforcement and screen against external electromagnetic impacts.
advantages:
– retained electric function of system within specified time
– halogen-free, no release of toxic and corrosive gases under fire
– reduced smoke manifestation under fire
– no flame propagation in vertical cable bundle, flame retardant
– resistant to oils and greases
– improved mechanical characteristics, resistant to scraping and vibrations
– smaller cable diameter and weight
